Application ined April 14, 191e. serial No. 91,042.

To all whom t may concern.'

Beit known that I, MATTHEW VIERENGEL, a citizen of the United States, and a resident of the cityof New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Vehicle-Tire, ofwhich the following lline 2 2 in Fig. 1.

is a full, clear, and exact description.

Among the principal objects which the presentinvention has in view are: to prevent total deiiation of a pneumatic tire when punctured.; to avoid the vinconvenience incident to the puncturing or leaking ofpneumatic tires; to prevent the disastrous'loss of air incidentl to the puncture of the wearing shoe of a tire; and to provide means for obtaining a maximum pressure of air in the tire. f

Drawings.

Figure 1 is a sectional elevation showing the side of a fragment of wheel and tire mounted thereon, the tire being constructed and arranged in accordance with the'present invention;

Fig. 2, is a cross section taken as on the Description.

As seen in the drawings, the tire is a unit structure in the sense that it dispenses'with an. inner tube. It depends, as do other pneuv matic tires, for its resiliency on air which is trapped or held under pressure within the tire. l

In thel present construction, a tire is A formedhaving a base flange 7, tread 8, connecting sides 9, and transverse partitions 10,.

arrangedt to form a series of chambers 11. The sidewalls 9 and partitions 10 are generally constructed` with a larg'e proportion of rubber, thereby .accommodating the com# pression and expansion incident to the serv# ice to which the tire 1s subject.

To enable the tire vto support in traffic thev for exerting transverse or lateral pressure on lips 16 of the tire, which operates to hold them under 'the inturned edges 14, as shown best in Fig. 2 of the drawings.

To prevent injurious puncture` of the tread 8, each of the chambers 11 is provided with an armor plate 17. The armor platesA 17 extend transversely across the tire to the full width of the chambers. Each plate 17 has inturned edges or sides 18, which serve to reinforce the partition lO'adjacent the tread 8 ofthe tire. The said plates are held in their position pressed outwardly against the tread portion of the tire, by means ofl air pressure introduced into the chambers 11.

When provided with a tire of the character disclosed, the operation of inlating the same consists in-introducing air under Y vpressure in relatively small quantities through each of the valves 12, to each of the chambers 11. It is obvious that while the structure necessitates that this operation be performed a number of times, the duration of the application is relatively slight. Therefore, the period of time required for the total inflation of the tire to the desired pressure, is about the same as now consumed in inflating tires of conventional'make.

1i The combination of'a tire comprising `integrally formed tread, base flange, side walls, and transverse partitions,-said partitions being spaced at intervals for forming air-holding chambers; means for independently inflating each of said chambers; and

means for preventing leakage from said chambers, said means comprising a nonpuncturable device disposed in said chambers adjacent thel outer walls thereof.

2. The combination of a tire comprising lintegrally foromed tread, base flange, side walls, and transverse partitions, said partltions being spaced at intervals for forming air-holding chambers; means for independently inating each-0f said chambers; and.

means for preventing leakage .from said I chambers, said means embodying a plurality'- of non-puncturable plates, one of said plates being` inserted in each lof said chambers adl jacent said tread, said plates bein'g directly acted upon by the air in said chambers.

3. T he combination of a tire comprising integrally formed tread, vbase flange, side walls, and transverse partitions, said partitions being spaced at intervals for forming air-holding chambers; means for independsaid sides being disposed in parallel relation 10 ently inlating each of said chambers; and to and in Contact with said partitions, and at means for preventing leakage from said opposite sides thereof for'- reinforcing the elambers, satid nlioeizmsletnbodyingf a purlity same. j

acted upon by. the `@tir in saidchambers and HARRY WILLIAM VIERENGEL,

being each provided with inturned sides, HENRY VI'ERENGEL.
